The Tandem t:slim X2 has been approved by the U.S. FDA as an "interoperable" insulin pump. An interoperable pump can be used with different components that make up diabetes therapy systems, allowing patients to tailor their diabetes management to their individual device preferences, which opens up huge future possibilities for closed-loop systems and other management technologies. In 2018, the Dexcom G6 was designated the first interoperable continuous glucose monitor by the FDA.
